...or you let out a loud smelly fart every time you told a lie?

Big nose or smelly farts?
Obviously neither option would be ideal, but if you had to go for one of them, which one would it be?

Just to clarify, if you go for the 'nose growing option' then it wouldn't be a permanent change.  After a minute or so, your nose would return to its normal size.  However, if you told a few lies straight after each other then your nose would grow each time you told a lie, before then returning to its normal size a minute or so after you finally stopped telling lies.

Obviously for some people like myself this scenario is irrelevant because of course I never tell lies, but for everyone else, which option would you go for?
